In Argentina in-pod peanut intended for use as seed for planting are stored from 3 to 6 months(from harvest to planting) where fungal contamination could increase resulting in a decrease of the grainquality during storage. However, only germinative power and vigor of the grains are normally evaluated,while sanitary quality is not considered. For this, the aim of this work was to evaluate the effect of pureBHA and in combination with their formulation (F-BHA) on peanut seeds stored in open containers inthe field. The experiment was carried out in a storage company of south of Córdoba, Argentina during2017. Two hundred kilograms of in-pod peanut treated with: Treatment 1 (T1) pure BHA (10mM);Treatment 2 (T2) the mix of pure BHA and F-BHA (5mM: 5mM); Treatment 3 (T3) pure BHA (5mM) at thebottom of the peanut container and F-BHA mix in the peanut and Treatment 4 (T4) untreated grains,were used. Fungal level, residues of BHA and fluctuations of temperature and humidity during 4 monthswere determined. Fungal count was significantly affected by treatment and time according to ANOVAtest (p
